IMPROVEMENTJN CAR-WHEELS.

The Schedule referred te in these Letters Patent. and making part of the same'g lBeit known that-I, HIEAM W. MOORE, of Jersey City, county of Hudson and'State of New Jersey,

have invented certain Improvements inGar-Wheels. The nature of my invention consists in additional improvements upon a car-wheel, for which Letters Patent were granted to ine June, 22, 1869, which specifies a cushion of wood as being inserted in a peculiar manner between the hub and the tread of the wheel, to destroy the metallic vibration between the tread and the hub, and thereby reduce, to a great extent, the noise arising from a solid wheel.

`In that invention, however, no means were provided for holding the tire o1' outer rim upon the inner wheel, should it become cracked or broken, but the pieces would instantly tif' eff tis'pm. the wood, and before there could he any indieanon of any danger.

These additional improvements are to'avoid this diti'iculty by the introduction of two flanges, one' on each rim ot' Aand B, as shown,A at C and D in section, and through these flanges' the clamping or binding bolts pass', thereby holding the two rims together, even though one or both of them might be cracked or broken.

.Description of the Dra-icing. Figure l is an elevation of my wheel, showing the outside, or that face opposite the ange.

Figure 2 is asection of same through the center ot the wheel.

venient manner, either in the'proccss of casting 'or upon a lathe,'and into said recess blocks of wood are fitted, as already specified in my previous patent.

I may here remark, however, that, in practice, I have found it very convenientto form the sides of' said recess with square corners, as at t, fig. 2, instead of a dovetail, as atd, so as to receivea tenen, but the principle remains the saine, both devices being merely to hold the wood in positionto be properly dressed for receiving the tire'or tread-rim of the wheel.

The outer rim or tread is vshown at B, figs. l and 2,- and made exactly as already specified in the previous patent,wiih the additionot. a flange, as at D, on its outer face, sufficiently deep to receive the binding or clamping bolts t t t which'draw the two metal portions of the wheel together. f

These bolt-s pass through said flange and a corresponding one, asat C, formed on the ri-ln of A, or the inner wheel, and. on its inner face,so that the two anges incluse the wood completely when the wheel is completed.

vBy the bolts passing thus through portions of thel outer and inner rims it'is manifest that both will, to'

saine degree, be held7 together, even if 'they should be cracked to such au extent as tol fall apart, if constructed as specified in my previous patent.

Claim.

I claim as my invention- The improvement upon my described car-wheel, consisting of the iang'es C and 1 constructed and applied as describer.
